Margaret is making strawberry milkshakes for the kids party. The recipe calls for 1/3 of a cup of strawberry syrup to make 10 milkshakes. How many cups of strawberry syrup are needed to make 90 milkshakes.?
To find out how many cups of strawberry syrup are needed to make 90 milkshakes, first calculate how much syrup is needed for one milkshake.
1/3 cup of syrup is needed for 10 milkshakes.
So, for one milkshake, 1/3 cup / 10 = 1/30 cup of syrup is needed.
To make 90 milkshakes, multiply the amount of syrup needed for one milkshake by 90:
1/30 cup x 90 = 3 cups
Therefore, 3 cups of strawberry syrup are needed to make 90 milkshakes.
